Issue Summary

Pressing to save a SLA config should trigger a graceful recalculation of SLA data for all issues - this is happening to only a sub-set of all issue.

Steps to Reproduce

1. Press save a SLA config
2. View SLA data in your instance

This does not seem to happen everytime, but when it does it's impact is big.

Expected Results

All issues with open SLA should have their SLA recalculated

Actual Results

Not all issues with open SLA have their SLA recalculated

Workaround

Empty save the SLA config again.
If this fails use the recalculate SLA endpoint
